During the study of anti-HIV-1 active components of the aqueous extracts of the roots of Salvia yunnanensis, three new derivatives of polyphenols, namely: methyl salvianolate A (2), ethyl salvianolate A (3) and cis-lithospermic acid (5) were isolated along with two known polyphenols, salvianolic acid A (1) and lithospermic acid (4) their structures were elucidated on the basis of NMR and MS spectral analyses. The anti-HIV-1 activities of the 5 polyphenols were tested for the inhibition of P24 antigen in HIV-1 infected MT-4 cell cultures and HIV-1 replicative enzymes in vitro.
在对云南鼠尾草根部水提取物的抗HIV-1活性成分进行研究期间,分离得到了三种新的多酚衍生物,即:丹酚酸A甲酯(2)、丹酚酸A乙酯(3)和顺式紫草酸(5),同时还得到了两种已知的多酚,丹酚酸A(1)和紫草酸(4),并通过核磁共振(NMR)和质谱(MS)光谱分析确定了它们的结构。对这5种多酚的抗HIV-1活性进行了测试,以检测其对HIV-1感染的MT-4细胞培养物中P24抗原的抑制作用以及对HIV-1复制酶的体外抑制作用。
